1. Basic safety precautions
1. Basic safety precautions
■ Read the instruction manual carefully.
● Understand functions of operation control equipment and
familiarize yourself with where it is and how to control it.
Also, have a proper understanding of how to operate and
meaning of each symbol.
■ Observe the rules in work site.
● Observe the established rules such as prohibitions in the work site, cautions, and work
procedures.
■ Wear clothes suitable for the work, and protective means.
● Wear clothes suitable for the work, safety shoes, and safety cap.
● Do not wear clothes which are likely to be caught in a projection of the machine, and/or
an ornament. Also, do not wear a clothe stained with oil as it may catch fire easily.
● Never forget to wear protective goggles and a mask when required in the work.
■ Handle with care when hot members are at high temperature.
● Take care not to be burned as the engine as a whole is very hot
during operation or immediately after it has been stopped.
● Do not allow your hand, body and clothe to be touched to the
muffler as it is very hot while the engine is running or immediately after it has been stopped.
● Take care, while the engine is still hot, not to be burned from oil
spray when draining or filling oil.
Be sure to observe the safety precautions to secure safety.
Failure to observe the precautions will
invite accidents or machine troubles.

1. Basic safety precautions
■ Pay attention to fire.
● Bringing a open flame close to fuel and oil may invite a fire.
In particular, fuel can catch fire very easily and it is dangerous.
● Do not bring a fire such as of cigarette or of match close to the
flammable materials.
● Supply fuel with the engine stopped after no fire has been confirmed around the rammer.
● Tighten the caps such as for fuel and for oil securely.
■ Pay attention to ventilation.
● Exhaust gas is harmful for your health. If the engine has to be
run in a room or in a poorly ventilated area, ventilate the area by
opening windows and/or entrances.
■ Check the machine body before operation.
● Check to see if each part of the machine functions properly at a safe place. If it is found
anything wrong, be sure to take corrective measures to start operating the machine.
● Check the machine for unusual noise, unnatural vibration, heat and smell. If it is found
something wrong, stop the machine at a safe place immediately and check and locate the
cause to repair it.
■ Be careful not to be caught in the machine.
● Do not stand close to the machine while operating the machine
because your hand, body, or clothe is likely to be caught in the
rotating members which may result in an injury.
Be careful not to be caught in the machine. Be sure to stop the
engine before performing inspections and maintenance for rotating members and their vicinities.

1. Basic safety precautions
■ Cautions to be taken when loading and unloading using a crane.
● Surely bind the guard with a wire rope
as shown in the figure on the right.
■ Cautions to be taken when loading and unloading the machine.
● Load and unload the machine in/from a transporting vehicle with two persons in order to
avoid an accidental drop of the machine.
● Drain fuel from the fuel tank, the carburetor, and the fuel strainer before transporting it
on a long distance or on a rough road.
When lifting up the machine by holding the handle, hold
the handle at its front and rear part to prevent your finger
and/or hand from being caught between the handle and the
machine body.

3.1. Engine
Refer to a separate Engine Operation Manual for the engine.
3. Inspection before operation
Oil gauge
Fill port
Drain plug
Maximum oil level
Minimum oil level
(Refill is required)
① Remove the oil gauge and wipe off oil
stuck on the gauge with a rag.
② Push the oil gauge against the oil fill port
without screwing it in to check oil level.
③ Refill oil until it comes to the upper limit
mark when the level is insufficient.
Be sure to check and refill oil with the engine held level.
Check the oil level again at approx. 3 minutes after it has been refilled.
Do not supply oil more than the specified since over-supply of oil may
result in blowing out of oil and poor output of the engine.
Shortage of oil may cause seizure of the engine.
If an oil other than the specified is used, service life of engine is likely to
be shortened.
•
•
•
•
IMPORTANT
Screw in the oil gauge securely after oil level has been
checked and refilled .
•
CAUTION
3.2. Checking oil in the engine chamber
10
3. Inspection before operation
Be sure to check and refill oil with the rammer shoe held level.
Run the engine for a while after oil has refilled then check the oil level
again at approx. 3 to 5 minutes after engine has been stopped. If oil has
been filled sore than the specified, malfunction results. Be sure to wipe it
off when over-filled.
If an oil other than the specified is used, service life of engine is likely to
be shortened.
•
•
•
IMPORTANT
Remove the fill plug located in the lower
cylinder case with the rammer shoe held
level and check that the oil is filled up to the
mouth of the port.
If it is found insufficient, supply oil to the
extent that it comes full to mouth of the
port.

3.4. Checking fuel
3. Inspection before operation
Remove the cap on the fuel tank to check
remaining oil visually. Refill fuel if it is
found insufficient.
Fuel to be employed:
Regular gasoline for automobile
Wipe off fuel thoroughly when it has been spilled out.
Be sure to stop the engine when filling fuel.
Tighten the cap on the fuel tank securely after fuel has been
filled up.
Be sure to check if it is the right fuel before refilling fuel.
•
•
•
•
WARNING
In order to prevent fuel from being blocked. be sure to fill up
fuel through a filter.
•
CAUTION
Since shortage of fuel can cause irregular tamping motion due to uneven
fuel supply to the engine by vertical (vibrating) motion of the machine,
refill fuel a little earlier.
•
IMPORTANT

3.5. Checking bolts and nuts for their tightness
Re-tighten bolts and nuts in each section after each operation and once a week.
Bolts and nuts are likely to become loose due to vibration of the machine body.
If it is operated with the bolts and/or nuts losened, malfunction and damage to the machine
may result.
In particular, be sure to check bolts and nuts securing tamping shoe before starting operation.
Since crankcase and its related members are made of aluminum, be careful not to over-tighten them.
•
CAUTION
3.6. Handle height adjustment
Handle height can be adjusted in two(2)
steps to meet the operator's height.
It can easily be adjusted by relocating handle counting bolts.
3. Inspection before operation
Although there are three (3) holes in the handle, do not use
the uppermost hole.

5. Operation
5. Operation
(1) Shift the throttle lever to Fully Open
position after the warm-up operation has
been completed.
Rammer starts ramming and moving forward.
Throttle lever
Open
During operation, do not lift up the machine by holding the
handle.
•
DANGER
Do not operate the engine with an intermediate speed as the
centrifugal clutch repeats ON and OFF in this speed which
may result in seizure of the engine.
Shift the throttle lever swiftly to Fully Open position.
If throttle lever is shifted slowly, it will cause irregular
machine motion and say damage clutch, springs, and tamping shoe.
Do not operate the rammer for driving a pile or on a solid
ground exceeding capacity of the machine such as surface
paved with asphalt, concrete, cobblestone, and solid rock.
Otherwise, this may cause damage to the machine as too
much stress is applied to the machine body.
Do not get your hands off the handle while operating.
When operating the rammer on a ground surface with a large
roughness and a large level difference, or on a steep slope,
take care that you will not be injured in your wrist due to
overturn or slip of the machine body.
In addition, this may cause earlier damage to the machine as
an excessive stress is also applied to the machine body.
Be sure to stop the engine before leaving the rammer unattended.

(1) Return speed control lever to the lowest
speed position and allow the engine to
run for 1 to 2 minutes for cooling.
Return the throttle lever swiftly as in the start-up operation.
Do not stop engine immediately after high-speed operation.
otherwise oil deteriorates or motion members are stuck fast
since the engine temperature rises suddenly.
